The outer wall of each wire 2 is covered with the shielding layer 10, but the end portion of the end of each wire 2 far from the housing is not covered with the shielding layer 10.

Referring to fig. 1, the plurality of wires 2 are collectively covered with a first heat shrinkable tube 51 at an end thereof close to the housing 11, and the first heat shrinkable tube 51 is also covered with the outer wall of the sheath 4 at an end thereof close to the housing 11. The ends of the wires 2 far away from the shell 11 are collectively coated with a second heat shrinkable tube 52, and the second heat shrinkable tube 52 is simultaneously coated on the outer wall of the end of the sleeve 4 far away from the shell. An elastic rod 3 made of carbon spring steel wire is arranged between the shell 11 and the sleeve 4, one end of the elastic rod 3 is fixedly connected with the shell 11, and the other end of the elastic rod passes through the first heat shrink tube 51 and extends into the sleeve 4. The first heat shrinkable tube 51 tightly attaches the elastic rod 3 to the plurality of wires 2 to perform a fixing function, and meanwhile, the first heat shrinkable tube 51 effectively reduces the cracking phenomenon at the end of the sleeve 4 close to the housing, and the second heat shrinkable tube 52 has the same function as the first heat shrinkable tube 51.

Referring to fig. 2 and 3, a fixing hole 7 is formed on a side wall of the housing 11 near the first heat shrinkable tube 51, and two fixing plates 8 are further provided on an inner wall of the housing 11 near the first heat shrinkable tube 51. One end of the elastic rod 3 close to the shell 11 penetrates through the fixing hole 7 and extends into the shell 11 to form a hook portion 31, and a hook tip 32 of the hook portion 31 is fixed between the two fixing plates 8, so that the elastic rod 3 is prevented from shaking in the shell 11.
